Technical field
The utility model relates to the synchronous electric main shaft of a kind of AC permanent-magnet, the synchronous electric main shaft of particularly a kind of dust seal type AC permanent-magnet.
Background technology
It is inner that the electricity main shaft time must consider that in design foul such as extraneous dust gets into electric main shaft vertically from the rotating shaft output of electric main shaft, pollutes the problem of electric main shaft internal environment.Present way is to adopt the sealing of " 0 " type circle at electric front-end of spindle.The shortcoming of this method: on the one hand, it is a kind of contact seal, when rotating ratio is higher, and serious wear, the sealing of " 0 " type circle was lost efficacy easily; On the other hand, if select high performance wear-resisting " 0 " type circle for use, cost is higher.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of dust seal type AC permanent-magnet synchronous electric main shaft.The dust seal property of the utility model is good, and it is simple in structure, easy to use, production cost is low, is convenient to promote the use of.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: the synchronous electric main shaft of a kind of dust seal type AC permanent-magnet; Comprise shell, p-m rotor assembly, stator module, rotating shaft, preceding gland and rear pressing cover, the front and back end of said shell is respectively arranged with front-end bearing pedestal and rear bearing block, and said preceding gland is positioned at the outer end of front-end bearing pedestal; Said rear pressing cover is positioned at the outer end of rear bearing block; Said rotating shaft setting in the enclosure, and said rotating shaft is respectively through being arranged on fore bearing and the rear bearing on the rear bearing block location on the front-end bearing pedestal, said p-m rotor assembly is arranged on outer casing inner wall; Said stator module is installed on the rotating shaft; And the position of said p-m rotor assembly and stator module is corresponding, and the front end of said rotating shaft gland in the past stretches out, and the rear end of said rotating shaft is provided with encoder; Be provided with between locking nut that moving axially of fore bearing limited and said locking nut and preceding gland gapped between said front-end bearing pedestal and the preceding gland; It is characterized in that: be provided with a plurality of annular grooves on the said locking nut and around said one week of locking nut, be provided with high temperature cloth in the said groove, be provided with the high temperature cloth chuck that high temperature cloth is carried out clamping in the said groove.
The above-mentioned synchronous electric main shaft of a kind of dust seal type AC permanent-magnet, said high temperature cloth are a kind of in Teflon high temperature varnished cloth, Teflon adhesive tape and the Kevlar tetrafluoro screen cloth.
The utility model compared with prior art has the following advantages: the synchronous electric main shaft of the described a kind of dust seal type AC permanent-magnet of the utility model; Through a plurality of annular grooves on the locking nut; And high temperature cloth is set in groove; High temperature cloth is very soft when being heated, and it forms the same thing of similar hairbrush of a lot of at the gap location of locking nut and preceding gland, and it contacts with preceding gland constantly; These many circle high temperature cloth are just formed a sealing that the labyrinth is the same, the very effective dustproof effect that plays.The good seal performance of the utility model, and it is simple in structure, easy to use, production cost is low, is convenient to promote the use of.
Through accompanying drawing and embodiment, the technical scheme of the utility model is done further detailed description below.
